Drives not showing while reinstalling Server 2012 R2

Server was hit with Wallet Dharma Ransomware so trying to format the server and reload Server 2012 R2. The server is an HP Microserver with two 2TB drives. It was previously running smoothly, prior to the virus. I've tried to reconfigure the RAID and even remove RAID. I removed the two 2TB drives and replaced with a single 3TB with no luck. I've tried to locate/load a driver for the WD Green 2TB and 3TB drives without any real success. Any help is greatly appreciated.
